• This section describes a modern homopolar rotary actuator with a ring
radially magnetized multipolar PM featuring a high-force density,
transverse flux configuration, which performs a spring action by develop
electromagnetic torques with limited-angular movement.
• The rotary actuator investigated features high-performance torque outp
because the actuator’s topology provides a magnetic torque gearing aff
• The torque level is proportional to the number of independent magneti
sections, which are equal to the number of stator teeth or magnet pole
pairs. Therefore, the total force developed by the actuator is the sum of
forces developed by each tooth-pitch section .
